Chains are indispensable auxiliary tools for mechanical power. Common chains include conveyor chains, suspension chains, etc. Since the chain is mostly used in industry, the quality of the chain should be carefully checked. The chain also needs to be maintained and maintained. Let me introduce you to the maintenance and maintenance methods.

The tightness of the chain should be appropriate, too tight will increase power consumption, and the bearing will be easy to wear; In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprockets is less than 0.5 meters, the allowable deviation is 1 mm; when the center distance of the sprockets is more than 0.5 meters, the allowable deviation is 2 mm. However, the phenomenon of friction on the side of the sprocket teeth is not allowed. If the two-wheel knitting is too large, it will easily cause off-chain and accelerated wear. Care must be taken to check and adjust the offset when replacing sprockets. The tightness of the chain is: lifted or pressed from the middle of the chain, the center distance of the two sprockets is about 2%-3%. If the new chain is too long or stretched after use, it is difficult to adjust, and the chain links can be removed according to the situation, but it must be an even number. The links should pass through the back of the chain with the cleats inserted outside, and the openings of the cleats should face the opposite direction of rotation. After the sprocket is seriously worn, it should be replaced with a new sprocket and a new chain at the same time to ensure good meshing. You can't just replace a new chain or a new sprocket alone.

 

When the chain is lubricated well, an oil film can be produced, which can protect the hoist chain from the influence of temperature while improving the sensitivity; adjust the length according to the working environment. If it is too long, the workload needs to be reduced, and overloading is strictly prohibited. Carefully check whether the tightness of the chain is appropriate, whether the lubrication work is done, whether the length is appropriate, and whether it is overloaded.
